Or near death experience. A glimpse of the next life. A lot of times you are surrounded by darkness and then you may see a small speck of light in the distance. Peolple will gravitate to the light and the light gets bigger and brighter. Some people may see a person or thing in front of this light. I believe that light comes from God. I saw that light with a thing in front of it. It was not a NDE though. I got it from a contemplation. Very good experience. I do no drugs or alcohol. To proceed further in the spiritual quest, do not partake in those vices. Negative experiences come from use of these vices. Smoking is another example.
A man recently had a NDE for 90 minutes and was terrified from it. All he saw was utter blackness. He said his mind shut down that experience to protect him. If you find yourself in that situation, don't panic. Everything is about the imagination. That's how things come to pass. The car came from an idea a person had and the imagination helped set the stage for it's fruition. Many people then can ad to that imagination. In this case making the car better. So back to this guy's NDE. Use your imagination and put the light in front of you also think of a loved one at the same time. The blackness will soon leave your vision. Always use your imagination no matter if you are on this side of life or the other side. It works.
